T/GDWCA 0004-2018 Thermoplastic Insulation Thermoplastic Protective Braid Cables

Scope

Scope: This standard specifies the terms and definitions, product models, product names, and product presentation methods, usage characteristics, general requirements for cable structure, finished cable testing, delivery length, inspection rules, marking, packaging, transportation, and storage of thermoplastic insulated sheathed cables. This standard applies to thermoplastic insulated sheathed cables with AC rated voltages of 30V, 60V, 90V, 125V, 150V, 300V, and 600V. Main technical contents: I. Usage characteristics 1. The long-term operating temperature of the model cable used should not exceed the rated temperature of the product. 2. The rated voltage of the product is the value specified in the product specifications, etc. II. General requirements for cable structure 1. Unless otherwise specified, the conductor shall be composed of unplated or plated annealed round copper wires or copper alloy wires, which may be solid conductors or stranded conductors. 2. When the insulation contacting the copper conductor is tested for corrosion of unprotected copper and no protective isolation layer is used, each single wire of the solid conductor and stranded conductor shall be covered with a suitable metal or alloy plating. 3. The plating on the stranded conductor is only allowed on the outermost metal wire when it is necessary to prevent the insulation layer from adhering to the copper conductor, rather than for corrosion prevention.
